-// This representation has a tendency to bloat - adding a small penalty to fitness such as "this.velocity - 0.000000001*String.len(this.genotype);"

-// removes "work in progress" changes in genotypes thus promoting immediate, straightforward improvements while hindering slower, multifaceted progress.

 // TODO getting rid of redundancy (valid genotypes with a lot of "junk code") in this representation looks like a good idea; many improvements to this end have already been done in April & May 2023, so maybe it is not a big problem now?

 // TODO the behavior of neuron input indexes during mutation seems badly implemented (see also TREAT_BAD_CONNECTIONS_AS_INVALID_GENO). Are they kept properly maintained when nodes are added and removed? This could be done well because during mutation we operate on the tree structure with cross-references between nodes (so they should not be affected by local changes in the tree), and then convert the tree back to string. Yet, the f4_Node.conn_from is an integer and these fields in nodes do not seem to be maintained on tree node adding/removal... change these integer offsets to references to node objects? But actually, do the offsets that constitute relative connection references concern the f4_Node tree structure (and all these sophisticated calculations of offsets during mutation are useful) or rather they concern the f4_Cells development? verify all situations in f4_Cell::oneStep(), case '['.
